However, due to factors such as long sailing distances, climate change and route differences, the temperature inside the cold box may fluctuate greatly. For example, long-distance sailing will cause the temperature inside the cold box to gradually increase, and seasonal changes in routes will also cause difficulties in temperature control. In addition, the temperature and humidity differences in different areas of the route will also affect the stability of the internal environment of the cold box.

[0003] At present, the cold box information collection system is limited by its own independent serial communication protocols, such as Lengxing, Lengwang and Daikin, which are not compatible. In addition, the power carrier form is also the development direction in recent years, but the power carrier involves the transformation of the peripheral communication circuit, and the communication speed is not real-time. The most important thing is that the above are all wired connections, which increases the cost and the difficulty of loading and unloading the cold box. Therefore, the cold box data collection system urgently needs an efficient, convenient and real-time communication method. Summary of the invention
